Application filed'February 2 4, 1908. Serial N 0. 417,260.

To all whom it may concern; I

Be it known that I, BERNDT A. Swanson, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Valve-Removers, of which the following is a specification.

My invention relates to devices intended to facilitate the removaL-disasse mbling and and adjacent arts of motors, 111d is partic- Its objects are those usua y sought in this class of devices; and the invention consists in the novel construction and combination of parts hereinafter described, andillustrated 1n the accompanying drawings, wherein Figure 1 is a side elevation of device in inoperative position. Fig. 2, a like elevation in operative position. Figs. 3 and 4, rear and lan elevations respectively of the same,

, and *igs. 5 and 6, sections on lines it w and y y 14, and abuts against the block, 16.

respectively ofFigs. 2 and 1'.

Like reference characters indicate like parts throughout the views.

My device is shown in conjunction with the usual motor parts, 1, the exhaust chamber, 2, the exhaust valve stem, 3, the cotter pin or key, 4, the valve spring, and 5 the spring washer.

My novel device comprises flatoblong body plate, 6, having'horizontal forwardly directed bearing fingers, 7, upon its upper end and guide rojections or lugs, 8, upon its lower end. T evbody, 6, is also provided with a vertically disposed slot, 9. Integral with the upper rear portion of the body is an.

extension comprising a horizontal base, 10', and parallel vertical side walls, 11, exonding from each side of the base and provided with vertical slots, 12, in which register the ends of a horizontal pivot pin, 13; loose in the upper end of a vertical rod, 14, hich passes loosely through an opening, 15, in a block, 16, and which is rovided upon its wer portion with three s, 17. A threaded thumb nut, 19, engages the threads, 17, of chi rod,

Splral spring, 20, surrounds the rod, 14. and abuts against the block, 16, and the extension base, 10. Fixed in the block 16, is a threaded pin or projection, 21, which passes through the slot, 9, and through an opening, 22, in a slide plate, 23, and has upon its end the cam near the handle. assembling of the exhaust valve. cotter pin,

a. retaining nut, 24. The vertical slide, 23, passes between the guides, 8, and has a iorizontal forwardly extending bifurcated foot, 25.

Fixed to the trunnion or pivot pin, 13, oif center is a cam, 27, in this-instance recessed shown in Fig. 1, with the shoe or fork, 25,

beneath the washer, 5, and the bearing members, 7, upon the exhaust chamber, 1. The handle, 29, is then elevated to the position as at 28, as shown in Fig. 5, and provided shown in Fig. 2, reversing the cam and bringing the portion, 29, to rest upon the base, 10, whereby the cam is locked in its elevated position. The elevation of the handle, 29, raises the rod, 14, block, 16, plate 23, and forked projection, 25, compressing the valve spring, 4, whereby the cotter pin, 3, may be removed, and the valve parts be disassembled. The distance of the fork, 25, from the fingers, 7, may be increased ad'usting the nut, 19.

Vhat I claim is, p 1. In a valve remover, the combination with thebody, of sup orting means upon the upper portion of the ody, a forked member slidably mountedin the lower portion of the or diminished by body, and cam means upon .the body operatively connected with the forked member for actuating said member.

2. In a valve remover, the combination with the body, of supporting means upon the upper portion of the body, an extensionupon the body, an operating cam mounted upon the extension, aslidable block upon the body,

-operative connections between the cam and the block, and a forked member slidably mounted upon the body and fixed to the block.

3. In a valve remover, the combination with the body, of supporting means upon the upper portion of the body, an extension upon the body, an operating cam mounted upon the extension, a slidable block upon the body,

.ja rod-iconnecting the cam and block, and a forked member slidably mounted upon the body andfixed to the block.

4. In a' valve remover, the combination vwith the body, of supporting means upon the i .u per portion of the body, an extension upon .t ebody an operating cam mounted upon theextension, a slidable block-upon the bod 'arod connecting the cam and the bloci i, means .upon the rod for adjusting the block with relation to the extension, and a forked vmember slid-ably mounted upon the body is theupper portion of the body, guides upon and fixed to the-block. 1

, 5. In a valve remover, thecombination with the body'-,,of an engaging flange upon- I the lower ortion of the body, an extension upon the 0d comprising a base andsidewalls provide with slots, an operating cam resting upon said base, a pivot pin in the,

i cam-registering in-the slots, a slidable block upon the body below-the extension provided I with an'opening, a rod traversing the opening and pivoted at one end to thepivot pin, an 1 thebody comprising a base andside walls provided with slots ,an operating cam having its lower face portion'resti'ng' upon the base, and provided upon its upper face with a'flattene portion, a pivot pin .in the cam ofi center and registering in the slots, a slidable' block upon the body,-a rod connecting the pivot 1n and block, and a forked member slidab y mounted upon the bodya'nd fixed to the block;
